Description
本发明属于涂料加工设备领域，具体为一种环保型粉末涂料挤出设备。The invention belongs to the field of coating processing equipment, in particular to an environment-friendly powder coating extrusion equipment.
粉末涂料是以固体树脂和颜料、填料及助剂等组成的固体粉末状合成树脂涂料。和普通溶剂型涂料及水性涂料不同，它的分散介质不是溶剂和水，而是空气。它具有无溶剂污染，100％成膜，能耗低等环保型的特点。Powder coatings are solid powder synthetic resin coatings composed of solid resins, pigments, fillers and additives. Different from common solvent-based coatings and water-based coatings, its dispersion medium is not solvent and water, but air. It has the characteristics of no solvent pollution, 100% film formation, and low energy consumption.
由于粉末涂料的导热性较差，内部热量无法散发出去，加速了粉末涂料各组分分子的热运动，导致粉末涂料的结团，同时如果包装袋中较高温度的空气冷凝到室温时，也有水分析出，二者共同作用的结果，致使粉末涂料受潮结块。并且在涂料投入进行加热熔融的步骤中，就需要对物料内含水进行严格控制，这样是决定其质量的关键因素之一。Due to the poor thermal conductivity of the powder coating, the internal heat cannot be dissipated, which accelerates the thermal movement of the components of the powder coating, resulting in agglomeration of the powder coating. The water analysis shows that the combined effect of the two causes the powder coating to be wet and agglomerated. And in the step of heating and melting the coating, it is necessary to strictly control the water content in the material, which is one of the key factors to determine its quality.
